Pseudorandom number generators are used in many areas of contemporary technology such as modern communication systems and engineering applications. In recent years a new approach to secure transmission of information based on the application of the theory of chaotic dynamical systems has been developed. In this paper we present a method of generating pseudorandom numbers applying discrete chaotic dynamical systems. The idea of construction of chaotic pseudorandom number generators (CPRNG) intrinsically exploits the property of extreme sensitivity of trajectories to small changes of initial conditions, since the generated bits are associated with trajectories in an appropriate way. To ensure good statistical properties of the CPRBG (which determine its quality) we assume that the dynamical systems used are also ergodic or preferably mixing. Finally, since chaotic systems often appear in realistic physical situations, we suggest a physical model of CPRNG.

MEMS rocket array is one of the most promising propulsion systems for micro satellite. Its recent development researches have reached close to practical devices. This paper reviews the performances and maturities of recently-build MEMS rockets. Four MEMS rocket projects are treated; LAAS-CNRS, France, Tohoku University, Japan, National University of Singapore, and Kyushu University, Japan. Their design, size, propellant, etc. are explained. The smallest MEMS rocket of Kyushu University using DDNP propellant and PDMS micro tank is also introduced.

The Problem A number of new perspectives of virtual human resource development (VHRD) have been provided in this issue of Advances in Developing Human Resources ( ADHR) that warrant further discussion. As VHRD is still a nascent area of inquiry in HRD, professionals need more explanatory examples and solutions to consider for determining their own role in working with people and technology. The Solution This article offers a synthesis of key constructs of VHRD from the articles in this special issue. Also, it provides a discussion around two different modes of technology development (TD) needed by HRD professionals in the contemporary technology-enabled environment afforded by VHRD. And, the integration of TD in addition to career development, training and development, and organization development is essential to the future of HRD and is discussed herein. The Stakeholders This article targets primarily practitioners interested in VHRD interventions and processes. It encourages the reader to examine the commonalities across the articles in this issue of ADHR and also to consider the new skills required for HRD professionals when seeking to align organizational mission with all levels of the organization.

Metal Additive

Purpose Additive manufacturing has been described as converting supply chains into demand chains. By focusing on metal additive manufacturing as a contemporary technology causing ongoing disruption to the supply chain, the purpose of this paper is to describe and discuss how incumbent firms act during an ongoing, transformational disruption of their supply chain. Design/methodology/approach Interviews and secondary data, along with seminars attracting approximately 600 individuals operating in metal additive manufacturing, form the empirical basis for this paper. Findings The findings of this paper indicate how disruption occurs at multiple positions in the supply chain. Episodic positions as conceptualised in this paper refer to how parties challenged by disruption attempt to reach normality while speeding the transformational disruption. Originality/value This paper contributes to previous research by theorising about episodic positions in light of a supply chain disruption. The empirical data are unique in how they capture supply chain change at the time of disruption and illustrate disruptive, transformational change to supply chains. The paper interlinks research on disruption from the innovation and supply chain literature, with contributions to both.

Water Level Contour

Geo-hydrology and groundwater exploration manner to pick out and to find the zone of recharge of groundwater in a precise river basin or a catchment .water level contour traces (or waft traces) are much like topographic strains on a map. They fully represent "elevations" in the subsurface. Water table contour lines can be used to inform which manner groundwater will glide in a given region. Plenty of wells are drilled and the hydraulic head is measured in each one. Water desk contours are drawn that be a part of areas of identical head .The ones water table contours lines are also called equipotential strains. Bear in mind: groundwater usually movements from a place of the higher hydraulic head to an area of decrease hydraulic head, and perpendicular to equipotential traces. In our challenge, we put into effect concept of water table contour map and geohydrological studies on Krishnagiri using GIS software program which plays the essential position in contemporary technology.

This book review compares two recent titles on copyright law: THE COPYRIGHT WARS: THREE CENTURIES OF TRANS-ATLANTIC BATTLE by Peter Baldwin, and COPYFIGHT: THE GLOBAL POLITICS OF DIGITAL COPYRIGHT REFORM by Blayne Haggart. Both books are meticulously researched and carefully written, and each makes an excellent addition to the literature on copyright. Contrasting both titles in this joint review, however, helps to reveal a few respects in which each work is incomplete; indeed, each book occasionally reads as a critique of the other. Baldwin’s book places contemporary debates in a much deeper historical context, but in so doing overlooks some of the unique challenges contemporary technology poses to the law as well as the historically unprecedented obstacles that contemporary law raises to some forms of socially valuable innovation. Haggart’s book, in contrast, maintains a narrower focus on the contemporary era, yielding a superior accounting of the institutional and social interests now at stake in the global copyright debate, but fails in some respects to appreciate the ways in which the much lengthier course of historical development constrains future copyright policy-making. The review concludes by suggesting some respects in which both books might serve as valuable guides for copyright policy-makers at both the national and international levels.

<p>This research explores how Māori tradition and narratives along with modern fabrication techniques can be used to make contemporary Māori design. The aim of this thesis is to document my work history and findings; and to add to the continuation of contemporary Māori design discourse. Part of the documentation process was interviewing leading Māori artists and craftspeople. This helped me to develop and reflect upon my tikanga (correct procedure), which in turn allowed me to create a body of physical works that fulfilled the compositional component of this thesis. There are two dominating components to my work: the engagement of narratives which I have a personal interest in and my use of new technologies to generate these works. The narratives used predominantly relate to my Māori cultural heritage and background. These stories have captured my imagination and I have enjoyed expressing them in a way that departs from the customary tribal style and creates a personal contemporary design approach that is distinctly my own.</p>
